Euroclay 2015 – Report

Clay and fine particle science has always been pursued across a wide variety of traditional scientific disciplines. The sessions that contributed to the programme of Euroclay 2015 reflected this broad reach of clay science and were aligned with three cross-cutting societal research themes: Energy, Materials and Environment and Health.

Clay science has always had close links with Energy research such as in the discovery and recovery of hydrocarbons, more relevant than ever as we strive for ever enhanced recovery and to tap unconventional sources such as clay-rich shales which arealso the focus of many concepts for the safe containment of nuclear waste.

As far as Materials are concerned, clay must qualify as the oldest branch of all materials science but it continues to define some of the newest material developments and probably ranks as the most important and versatile of all of man’s industrial minerals with a wealth of modern applications and uses.

Environment and Health are also key areas where clay research has much to contribute to society. Careful but innovative management of soils will be key to future food and water security as population pressures increase; and we are only beginning to make a modern exploration of the many interactions and uses of clay minerals in relation to health.

The sessions and symposia at Euroclay were assembled with these three themes in mind and the scope of some was spread across all three. We also endeavoured to engage related disciplines that sit around the periphery of our clay world knowing that we inevitably all profit from such interaction; layered compounds generally and zeolites in particular share many commonalities. And finally there were many general sessions to accommodate the additional breadth and wealth of clay topics that define modern clay science.

520 delegates gathered in Edinburgh from 5-10th July 2015 for the joint Euroclay-CMS meeting. To begin: some statistics - 440 presentations; 128 students; 52 countries represented; 16 keynotes; 6 plenaries; 5 parallel sessions on each of four days; 5 field trips; 1 short course; 1 workshop; 2 poster sessions; many people who learned Scottish dancing for the first time; and many who grew to appreciate the smoky single malt of Islay during the Whisky tasting event!

The scientific program of EUROCLAY 2015 brought together, in an exciting, leading-edge programme, specialists from different disciplines related to clays and clay minerals. It consisted of technical sessions of both oral and poster presentations with a generous quota of invited speakers who are the leaders in their respective fields. A key aim was to integrate industrial and academic workers, with sessions which covered both areas arranged around three societal themes where clay research flourishes, namely ‘Energy’, ‘Materials’, and ‘Environment and Health’.

Fieldtrips:

The Euroclay-INZA Pre-Conference Field Trip to Strontian and Mull (led by Linda Campbell, Alan Dyer, Oneta Wilson and Craig Williams)

Account by Linda Campbell

To mark The International Natural Zeolite Association’s involvement with Euroclay this year, a 6-day field trip was run, focused on Scottish natural zeolites. Scientifically and socially, highlights reported from the group included the spectacular array of common and rare zeolites examined, not least the Sr-Ba-zeolite brewsterite and Ba-zeolite harmotome (Strontian Mines), and other minerals; saponitic clays (raised in profile due to Martian mineralogy), sapphire, mullite and strontianite. Mining operations were ‘well-and-truly experienced underground’ at Lochaline Quartz Sand Mine, after vitreous analcime crystals bordering a basalt dyke were collected by torchlight. The international group rapport was excellent, with enthusiastic students, spouses and seasoned professionals all contributing something distinctive. Together, they survived the icebreaker-quiz evening, a whisky distillery, dips in the Atlantic and at the spa, and braved the sea-boat tour under leaden skies to Staffa’s breath-taking exposures of basalt columns. A final night dinner overlooking the Sound of Mull culminated with a last chance to enjoy the very long daylight hours and a beautiful sunset at ~23.00. The trip leaders, (“Seat-belts please!”) were extremely well-supported by a magnificent group!

We are pleased to acknowledge the mining-industry personnel who provided access, information and support; Tim Smith (Nippon Sheet Glass Co. Ltd.), Diego Zurolo and colleagues (Minerali Industriali, Lochaline), Dan MacDonald (Strontian).

THE DEVONIAN–CARBONIFEROUS FIELD EXCURSION AT EUROCLAY 2015, EDINBURGH

Account by C.V.Jeans

Planning started late in 2011. The challenge of Edinburgh and the Borders was to find a visually and geologically exciting focus with potential interesting clay mineralogy. Having neither ventured as a stratigraphical clay mineralogist farther back than 250 Ma in time nor within 100 miles of Edinburgh …and as there are no respectable sediments of such a youthful age in the region… my suspicions were that any really interesting relationships there might have once been there during the early history of the sediments, will have long since been metamorphosed out of existence. With this in the back of my mind I consulted my good friend, the great palaeontologist and teacher Euan Clarkson with his unrivalled knowledge and enthusiasm for the Borders. He confirmed that the Old Red Sandstone and the overlying Carboniferous were not only a feast for the eyes but were well exposed in the spectacular coast line of Berwickshire and East Lothian. A hospitable stay with Euan and his wife Cynthia and an exploratory fieldtrip accompanied by a delightful Slovak student Jana Meixnerova convinced me that even without any clay mineralogy it would be difficult to avoid being swept off one’s feet by the spectacular coastal scenery. In addition there was the attraction that the Borders were steeped in the history of a fairly lawless land in the extended battle between the Scots and the English.

North of the Border only a limited amount of serious stratigraphical clay mineralogy has been practiced, although many fine studies have been carried out on these ancient sediments as parent material for soils. So it was with some trepidation that I started in 2012 looking systematically for varying patterns of clay mineralogy in the transition from the red continental Old Red Sandstone facies to the reefal and coal measure facies of the overlying Carboniferous. My fears were related to two matters. First my home base is 540 km distant from Edinburgh and the logistic difficulties of really getting to know the sequences were considerable. Second, Cambridge is no longer the place where systematic stratigraphical clay mineralogy is easy to do. The frontiers of Earth Sciences have moved on to other matters…. the ever reliable and user friendly old workhorse, the Philips diffractometer, has been sent into retirement. For nearly ten years there has not been an effective system for this type of work. However, somehow or other …with a combination of help, frustration and patience the general clay mineralogy of sixty or so samples was achieved. The results were only just a little better than my worst expectations! There was little evidence of any lithofacies controlled clay mineralogy or of a historical record of clay mineral changes preserved in the early cemented parts of the sediments in spite of the very variable lithologies. Here and there were clear signs of possible metamorphic effects. However there was enough variation independent of lithology and stratigraphy to consider it possibly worthwhile taking the project onto a further stage. It was with this mind frame that I decided that the fieldtrip had to be a geological and scenic feast for the eyes and mind and the field guide had to reflect this. To get the best out such a trip, the field party should already be in the right mind frame to experience the historical and geological significance of this region of the Borders and its rocks.

Activity started the evening before the day of departure. A talk on the geological and palaeontological significance of the Devonian- Carboniferous transition and recent work being carried out by various University departments and the British Geological Survey, was followed by a brief introductory talk on safety matters. This was followed by a Borders performance with Burns readings by Euan Clarkson dressed in full formal kilt in a matrix of Border music played on the accordion and the fiddle.

July 8th broke heavily overcast. By 8.30am gentle rain had started, the complete party of 32 with their packed lunches and having signed away their rights to sue any of the five leaders of the trip were encoached with their safety gear threatening to fall out of the overhead lockers,! A last moment realisation that a little extra food might be a useful safety net to avoid starvation meant that we left only 20 minutes late. The mood was good and bubbly. The local driver…Mr Drew Simmie from Berwick… eased the coach out into the morning traffic leaving the City on the A1 for the south. The party consisted of 27 guests from all parts of the World….China[7], Russia[3]. Croatia[2], United States[1], Poland[1], Netherlands[1]. Turkey[1]. South Africa[1], Iran [1], Switzerland[1], Korea[1], France[3], Germany [1], Czech Republic[1], Austria[1] and the UK [7]. There were five leaders, the two old men… Chris Jeans and Euan Clarkson…and three youngsters …Elena Kuznetzova, aide de camp and official photographer….Jenny Huggett, the official historian and roving host…. and David Wray, the party’s sweeper. In spite of the rain Euan managed to provide a running commentary on various geological and archaeological features as the coach made good time with the weather improving towards Berwick on Tweed. By the time the party had reached its outskirts the rain had stopped, the skies had broken into a wonderful skyscape of scudding cumulus clouds and blue skies with only the very occasional light shower of warm rain … and this followed us for the rest of the day. We entered Berwick through the town gates with Jenny providing a lively commentary on the complex history of the town in the struggle between Scotland and England with it changing hands 13 times. Mr Simmie did us proud showing off his home town so strikingly situated on the northern edge of the River Tweed’s estuary and its dominantly Elizabethan fortifications. He guided the coach not only through the old town and over the Tweed on the 1611-1624 stone bridge to the south side but then returned using the more modern concrete bridge(1920s) that provides fine views of the old fortified centre on the northern bank.

Not only the weather but fate had been kind to us. High tide was at 08.00 and by the time we had reached our first location, Burnmouth, a delightful little fishing port down a hair-raisingly steep road, we were already on a falling tide that gave us easy access to the finest coastal exposures of the Cementstones [Ballagan Formation]— the transitional facies between the continental Old Red Sandstone and the somewhat younger overlying marine Carboniferous sediments. From here we went to Cove, a former fishing village pitched high above its minute but still active harbour. A 15 minutes walk brought us to our picnic spot at Heathery Heugh overlooking Cove’s harbour and the swirling Carboniferous Calciferous Sandstone Measures exposed in the intertidal zone with the Torness Nuclear Power Station visible on the horizon. Having eaten our packed lunch and drunk in the spectacular views we continued our cliff top walk to Pease Bay. This bay has a fine sandy beach and spectacular headlands of red cliffs made up of the Upper Old Red Sandstone, although this fine situation is shared by a well organised but extensive caravan site with facilities that were of considerable use to the party! While inspecting the northern headland the party was caught by a short shower of warm rain which did nothing to dampen their enthusiasm. Picking up the coach again we retraced our steps to Eyremouth and to the visitors’ centre at St Abb’s Head, a nature reserve where awaiting us was a 16 seater coach driven by Tommy Dixon that could negotiate the narrow track up to the St Abb’s Head with its light house. This nature reserve is of national importance. It is centred around a dissected Middle Devonian volcano exposed on the coast that is faulted against low-grade metamorphic sediments of Silurian and Ordovician age. Not only are the cliffs spectacular but they are the favoured nesting sites of tens of thousand of sea birds. The party split into two for the rest of the trip. The first one led by Euan Clarkson, the second by Chris Jeans. Before separating our official photographer, Elena, carried out her duties admirably. The thirty minute wait for the second group meant that a welcomed cup of tea could be enjoyed at the visitor’s centre before the coach returned for its second visit to the Head. The final stop was at White Sands to view the intertidal reefs where the Carboniferous coal measure cycles are spectacularly exposed. The cycles demonstrate the transition from sandstone through to reefal limestones, soil beds and coals and brackish and non-marine muddy limestones. Again the fates were kind, when I returned three days later to collect samples of the Palaeosoil bed above the Middle Longcraig Limestone for Tatiana and Andrey Alekseeva…. most of the section was hidden by a thick cover of fucoid seaweed blown by the onshore wind….Even this had it good side, the samples were still collectible but now there was time to admire the very colourful limestone flora growing on the grassy tops of the low cliffs and recall how kind fate had been to us.

Bentonites: linking clay science with technology

George E. Christidis, Technical University of Crete, Greece

Stephan Kaufhold, BGR, Hannover, Germany

Don Eisenhour, Mineral Technologies Inc. Illinois, USA

Bentonites are very important industrial clays, which are valued by the industry due to the unique properties of smectites. This symposium invites presentations which deal with all aspects of bentonites, from the geological, mineralogical and geochemical characteristics of deposits, to the determination of physical properties, possible processing/activation routes and commercial applications. Of particular importance are the characterization of bentonite deposits consisting of dioctahedral or trioctahedral smectites, the description of mineralogical and chemical heterogeneity within bentonites, and the determination of key smectite properties, which control both conventional and novel industrial and environmental applications.

Developments and applications of quantitative analysis to clay bearing materials, incorporating ‘The Reynolds Cup School’

Michael Ploetze ClayLab Zurich, Switzerland

Reinhard Kleeberg TU Bergakademie Freiberg, German

Mark Raven CSIRO, Urrbrae, Australia

Helen Pendlowski The James Hutton Institute, Aberdeen, Scotland

Because of their effects on the physical and chemical properties of rocks, soils, clays, and industrial materials, and because of the genesis and history information they record, knowledge of the types and relative amounts of clay minerals and other poorly ordered minerals is essential in many academic and industrial endeavours. Methods of quantitative phase analysis (QPA) represent, therefore, important tools e.g. in mineral exploration and processing, in clay science, and material science to name a few. This session invites contributions on QPA by any available method such as diffraction, spectroscopy, chemical analysis, or microscopy or combination of methods and approaches. Papers on methods and procedures as well as applications of QPA procedures, in soil, geological and materials science are encouraged. The session will conclude with ‘The Reynolds Cup School’, a series of invited presentations and extended discussion outlining best practice in procedures and strategies to obtain QPA of ‘state of the art’ quality with today’s most widely available tools and to discuss ways to address the many challenges that still remain.

Hyen-Goo Cho Gyeongsang National University, JinJu, Korea

The Asian Clay Research Group was organized through the Nagoya and Seoul meeting in 2010 and 2012. We plan to hold the 3rd meeting in Guangzhou in 2016. Our first participation in The CMS meeting in College Station, Texas, USA (2014) was successful in terms of communicating/collaborating with other clay minerals groups. The purpose of this session, held as part of the Euroclay2015 meeting, is to bring active Asian clay scientists together and promote scientific communication and interaction with the international clay minerals community. We invite papers on, but not limited to, biotic and abiotic reactions in natural environments that impact a number of geological and environmental process, such as sediment diagenesis, colloid transport, and the mobility and the ultimate fate of organic and inorganic contaminants. Topics also include the science and technologies of industrial clays, including exploration and clay resource development, particle engineering from macro to nano, and chemical and physical modification.

Environmental pollution is a growing public concern worldwide as society industrialises and citizens become more aware of the associated risks. Despite many resources being channelled towards the development of technologies for cleaning up contaminated environments, millions of contaminated sites still exist in sensitive locations because of the prohibitive cost of remediation or the lack of an effective technology to clean up sites to a level required by regulators. As a result, much scientific effort is being directed at developing new technologies which are both efficient and inexpensive. Natural materials such as clay minerals, which are inexpensive, highly adsorptive and available ubiquitously in all continents, hold great potential as environmental materials, both with and without modification. This symposium will highlight recent research advances in clay minerals-based remediation and remediation technologies including modified and non-modified clay minerals, redox active clay minerals, layered double hydroxides, bacteria supported clay minerals, and other novel fine particle based materials.

Nowadays, investigation on polymer-clay nanocomposites is already a well-established area of research that attracts scientists from both basic and applied research fields. For many years, smectites were the chosen clay for the preparation of those nanocomposites but now other types of clays minerals, such as kaolinite, nanotubular halloysite or microfibrous sepiolite and palygorskite are increasingly used in the preparation of polymer-clay nanocomposites.  Additionally, polymers of natural origin are more and more employed in the development of the so-called bionanocomposites or green nanocomposites.  In this way, the use of special clays and/or biopolymers make possible the incorporation of new properties and functionalities in the resulting nanocomposites. This session intends to be a forum for the latest research on nanocomposites focusing on innovative advances related to materials based not only on smectites but also on other types of clay minerals from kaolinite to fibrous clays, as well as related materials (e.g., layered double hydroxides), involving both synthetic and natural polymers.

Bioreactive clay minerals: impacts on environmental and human health

Lynda B. Williams Arizona State University, USA

Humans and animals have historically used clays to aid in digestion, protect skin, heal wounds and soothe musculoskeletal ailments. Pharmacopeias from the 17th century highlight medicinal uses of clay minerals, yet the mechanisms by which clays can be healthful or detrimental remain largely unknown today. Nano-technological advances in the last decade have revitalized research on the interactions of clays in mammalian systems. In this session we invite research that highlights new insights on the roles of bioreactive clays affecting human health. In particular we encourage research on medical or veterinary applications of clays and the mechanisms by which clays are beneficial or detrimental. Topics may include uses of clays in drug delivery, pelotherapy, hemostatic wound dressings, geophagy, antibacterial clays and clay toxicology. An important focus is the application of novel solutions to promote environmental and human health.

Over the last decade or so, structural characterization of layered compounds has benefited from the intrinsic evolution of the commonly used techniques (TEM, XAS, XRD, etc), and especially from improvements in quantitative methods of data analysis. In particular, the collation of experimental and computational results allowed reciprocal improvements of both approaches. Significant progress has come also from the combination of experimental approaches allowing for a thorough characterization of complex and/or very defective lamellar structures, including natural materials and mixed-layered materials. This session will be devoted to the recent advances of individual techniques, and to new possibilities offered by their combination. New structural interpretations, dynamical properties, and insights into the formation and evolution of such materials in natural environments are also relevant. Materials of interest include, but are not limited to, phyllosilicates, layered oxides, layer double hydroxides, and layered compounds in general.

Atsuyuki Inoue Chiba University, Japan

This session focuses on the many geological occurrences of chlorite: from soils to detrital sediments, to sedimentary and diagenetic systems, to hydrothermal alterations and to low- and medium-grade metamorphic rocks, chlorite is everywhere. It forms as pure grains, or as interlayers with phyllosilicates such as smectite, serpentine, and vermiculite. The aim of this session is to bring together those with an interest in chlorite in any of its many forms, to present data from a wide variety of different analytical techniques, and to promote awareness of the complexity of chlorite and above all the potential for it to provide new and useful information on many geologic processes from the surface of the earth to deep in the crust.

Argillaceous media are being considered as potential host rocks for the final, safe disposal of radio-active waste, and/or as major constituent of repository systems in which wastes will be emplaced. In this context clay radwaste scientists examine various argillaceous rocks that are being considered for the underground disposal of radioactive waste, ranging from soft clays to indurated shales. In addition, the shale gas and oil community is interested in the characterization of sediments and black shales from the core- to nano-scale, focusing on clay/brine/organic interfaces and understanding how pore space evolves and affects the transport and production potential of the shale system. Through characterizing fundamental properties such as nano-/micropore connectivity, all the way up to understanding transport and mechanical fracture properties of whole-rock units, both communities are studying the geological materials with a shared set of tools, from quantum mechanics computer simulations, through advanced microscopy and diffraction methods, up to triaxial mechanical tests and large-scale transport models.

Clay minerals are present in hydrocarbon source, reservoir and seal rocks and therefore characterizing their presence and properties plays an important role in understanding petroleum systems. For this session, we call, in particular, on papers that bridge the gap between research and everyday ‘Exploration and Production’ applications and issues - for both conventional and unconventional hydrocarbon accumulations – related to: rock characterization, log response calibration, drilling, diagenesis, reservoir performance, seal integrity, provenance, shale brittleness, fracture properties, organic-matter interaction, palaeo-thermometry, basin modelling, seismic response, rock physics modelling, oil sands bitumen recovery, oil-sands tailings processing, and enhanced oil recovery processes etc.

As analytical methods such as atomic force and scanning electron microscopy increasingly provide nanoscale information about processes occurring in layered minerals, the atomic resolution of computer simulation methods has become a natural adjunct to understand processes and structure at clay surfaces. Electronic structure simulations provide insight into redox processes, chemical reactivity at surfaces, and allow comparison with spectroscopic methods. Molecular mechanics approaches, where electrons are not included, are allowing the study of increasingly large systems and longer timescales. As well as structural properties, phenomena such as adsorption, ion effects and thermodynamic properties are increasingly extracted from such simulations. In recent years, these methods have been coupled together, along with coarse-grained molecular dynamics (where groups of atoms are coalesced) and phenomena such as intercalation or exfoliation may be studied. This session will provide an up-to-date overview of computer simulations applied to layered mineral science.

Natural zeolites – environmental, biomedical and industrial applications

Aleksandra Dakovic ITNMS, Physico-Chemical Laboratory, Belgrade, Serbia

Linda Campbell The University of Manchester, UK

Natural zeolites are microporous hydrated aluminosilicate minerals having countless technological applications due to their unique physicochemical features such as cation exchange, selective adsorption, molecular sieving, catalysis, etc. As far as cation exchange is concerned, natural zeolites have been largely investigated for ammonia and heavy-metal removal, although modification of these minerals with long-chain cationic surfactants enhances their adsorption properties towards anions and low polar organic contaminants. In addition, they have also recently been considered as carriers of pharmaceutical-active ingredients. This session is designed to promote discussions on these topics but also on other interesting technological applications including water and wastewater treatment, soil remediation, treatment of radioactive waste, as well as application in the veterinarian, pharmaceutical and industrial sectors.

Clays in the Critical Zone: soils, weathering and elemental cycling

Paul A. Schroeder University of Georgia, Athens, USAJason Austin University of Georgia, Athens, USABruno Lanson Univ. Grenoble Alpes, FranceSteve A Banwart University of Sheffield, UK

The “Critical zone" or CZ, includes the porous places extending from treetops to the bedrock, and more especially soils where organisms interact and shape the Earth’s surface over timescales from seconds to eons. Clay minerals and finely divided oxides are significant players within the CZ. In particular, they are known to be key in the fate of elements (both nutrients - including carbon - and pollutants) and molecules (e.g. pesticides but also drugs
